Answer:
The correct answer would be - C) the shape of a molecule determines how it functions in chemical reactions
Explanation:
The molecular shape of the molecules is one of the important characters of the molecules. It is important due to the fact that molecular shape determines how a molecule will react and interact with other molecules.
The shape of the molecules determines boiling point, melting point as well as various chemical reaction by determining the bonds. For instance, H2O or water has a tetrahedral shape which affects its bonding and properties. If molecules were linear in shape there would be no life existed.
Thus, the correct answer would be - C)
I think that correct answers are:
<span>Some of them lose their leaves in winter. (i.e. <span><em>Larix</em></span>)</span>
<span>They include the tallest plants (i.e<em>.Sequoia)
</em>I don't think they are the oldest type of seed plants, since in the past the classes like progymnosperms and seed ferns existed prior to the gymnosperms. But question isn't absolutely clear to me and I can't be 100% sure.
All of the gymnosperms have seeds unless human grows some seedless variant.
Gymnosperms don't have flowers like angiosperms do, but some people think that cone is kind of flower.
Male cones produce pollen, not female.
Hope I helped :)

Yes it is absolutely true that each lung is fed oxygen by a separate bronchus. There are actually two lungs and two bronchi. Each of the two lungs are safeguarded by the two ribcages as
they are placed within the rib cages. The lungs actually consists of elastic
sacs that contract and expand for taking in and releasing air. This way oxygen
is passed into the blood and carbon dioxide is taken out from the blood and
passed out. This is also the main function of the lungs.
